Israel's military chief said Thursday that other countries have readied their armed forces for a potential strike against Iran's nuclear sites to keep Tehran from acquiring atomic weapons.

Lt. Gen. Benny Gantz did not specify which nations might be willing to support or take direct action against Iran. Still, his comments were one of the strongest hints yet that Israel may have the backing of other countries to strike the Islamic Republic to prevent it from developing nuclear arms.

"The military force is ready," Gantz said. "Not only our forces, but other forces as well."

"We all hope that there will be no necessity to use this force, but we are absolutely sure of its existence," he told The Associated Press, adding that he was not speaking on behalf of any other nation.
